Two woodcutters

Two woodcutters somehow argued which of them would chop more wood from the morning until four o'clock in the afternoon.
In the morning the men dispersed in their positions.

At first they worked at the same pace. But an hour later, one of them heard the second stop chopping down a tree. Realizing that this was his chance, the first lumberjack redoubled his efforts.
Ten minutes passed, and he heard that the second woodcutter set to work again. And again they worked almost synchronously, when suddenly the first lumberjack again heard his opponent stop again. Once again, the woodcutter rejoiced to get to work, already feeling the smell of victory.
And so it went on all day. Every hour one of the lumberjacks stayed for ten minutes, and the second continued to work. When the time was up, the one that worked without ceasing was quite sure - the prize was in his pocket.
What was his surprise when he learned that he was mistaken.
- How did it happen? He asked his partner. “Every hour I heard you stop working for ten minutes.” How did you manage to chop up more wood than me? It's impossible!
“In fact, everything is very simple,” he said bluntly. - Every hour I stayed for ten minutes. And while you were still chopping wood, I was sharpening my ax.
